| Short description | Complex microphyll vine forest on alluvial plains |
| Structure code | Closed Forest |
| Description | Complex microphyll vine forest. Typical canopy species include Excoecaria dallachyana, Archidendropsis thozetiana, Polyalthia nitidissima, Drypetes deplanchei, Ficus rubiginosa, Diospyros geminata, Coatesia paniculata, Flindersia australis, Alectryon connatus, Alectryon subdentatus, Diospyros humilis, Planchonella cotinifolia, Bridelia leichhardtii, Croton insularis, Denhamia pittosporoides, Notelaea microcarpa and Siphonodon australis. Casuarina cunninghamiana may occur in scattered patches or low densities along channel banks. Emergents of Araucaria cunninghamii and Eucalyptus tereticornis may occur. Typical sub-canopy species include Mallotus philippensis, Gossia bidwillii, Alangium polyosmoides subsp. Tomentosum, Exocarpos latifolius, Hodgkinsonia ovatiflora, Capparis arborea and Pleurostylia opposita. Typical shrub species include Murraya ovatifoliolata, Alchornea ilicifolia, Turraea pubescens, Alyxia ruscifolia and Psydrax odorata. Occurs on Quaternary alluvial plains and channels in drier western parts of bioregion typically draining from hills and ranges. Riverine. (BVG1M: 4b). |

| Special values | 12.3.21: Important for fruit-eating birds, many of which migrate seasonally from upland to lowland rainforest. |
| Fire management guidelines | INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Do not burn deliberately. Protection relies on broad-scale management of surrounding country. May need active protection from wildfire in extreme conditions or after prolonged drought. Planned burns should not create a running fire into vine forest. Ensuring conditions of good soil moisture and moisture of litter in surrounding communities will limit fire behaviour/intensity. ISSUES: Fire sensitive and not normally flammable. There may be issues with lantana and other weeds from fire and other disturbance. Remnants may be limited by frequent fire at the margins. |
| Comments | 12.3.21: Previously mapped as 12.3.1. Found in drier environments than 12.3.16 and 12.3.17. Restricted to dry western parts of bioregion. Extensively cleared for agriculture. Prone to invasion by weeds such as camphor laurel Cinnamomum camphora, broad leaved pepper tree Schinus terebinthifolius, cat's claw creeper Dolichandra unguis-cati on margins and when disturbed. |
